Flame Synthesis of nanoparticles
Okonkwo et al., (2022). J. Am. Ceram. Soc. 105, 2: 1481-1490.

Nanoparticles are synthesized for various applications including catalysis by flame synthesis. Flame synthesis is a rapid scalable continuous single step method for nanoparticle synthesis unlike conventional wet synthesis methods. Currently we are focused on the synthesis of catalyst for carbon dioxide conversion in products of value.

Investigation of particulate matter formation in pressurized combustion systems
|
Staged pressurized oxy-coal combustion (SPOC) technology has been demonstrated to reduce the cost and energy penalties associated with carbon capture. To help design the scaled-up SPOC systems, we focus on the study of the resultant particle size distribution in pressurized combustion systems as a function of various operating conditions. This is important for several reasons: a) establishing the governing radiative heat transfer which is a function of particle size and other optical properties; b) the fouling characteristics of the resultant ash particles with a range of size dependent compositions; c) capture efficiencies of the downstream particulate control systems and the optimal operating conditions to minimize emissions.
